The valve inspection can be performed while the valve is still piped in line.
The Valves to be inspected may be:
The Fill Line Valve

The Drain Valve (pre 2005)
The Main Chamber Valve (Pre 2005).
1. Unplug the Aqua Phase from the power Supply
2. Turn off the water supply to the Aqua Phase
3. Loosen the Fill Line connection (to release water pressure).
4. Remove the Retainer clip or Cap
5. Remove the Data Label Plate if an Asco Valve.
